Used industrially for dehairing hides, wool pulling, ore flotation, metal refining, engraving, cotton printing, in the manufacture of paper, pharmaceuticals, rubber, and sulfur dyes. It is used in production of heavy water for nuclear reactors. 

Remove the wool from the tubes leaving as much of the solvent behind in the tubes as possible (it can be squeezed with a glass rod as it is pulled from the tube). 

The apparatus consisted of a U-shape glass volatilization pipe preheated to a designed temperature, a nose-only exposure unit containing six mice, a glass wool trap (packed with 0.5 g of glass wool fiber) that sequestered the vaporized test compound, and a vacuum system that created negative pressure and pulled the air through the...

When the a helices in wool are stretched, intrahelix hydrogen bonds are broken as are some of the interhelix disulhde bridges maximum stretching yields an extended P sheet structure. The Cys cross-links provide some resistance to stretch and help pull the a helices back to their original positions. In silk, the P sheets are already maximally stretched to form hydrogen bonds. Each P pleated sheet resists stretching, but since the contacts between the sheets primarily involve van der Waals forces, the sheets are somewhat flexible. 

Another approach, by Robbins and Crawford [166], is a modification of the Garcia-Wolfram method. In this system, the bulk of a hair assembly is assessed by measuring the work required to pull the tress through a succession of very thin (0.076 cm) circular templates of decreasing diameter. A plot of work values versus circle diameter is extrapolated to zero work to obtain the maximum tress diameter. This parameter appears to be a measure of the bulk of hair assemblies. Blankenburg et al. [168] of the German Wool Research Institute has independently developed a similar method using this principle.
